Life Prediction of Creep-Fatigue Interaction under Multiaxial Stress

Analysis of experiment result of low-cycle tension-compression, torsion and tension-torsion fatigue with holding time has been done. The main factors of influencing failures of combined creep and fatigue under multiaxial stress and high temperature are re'examinated, and the simple model calculating method to predict the fatigue life are worked. It is verified that calculating method has a good practicability.
